Subject: [GIT PULL] xfs: new code for 5.10, part 1
Message-ID: <20201014205059.GD9837@magnolia>

Hi Linus,

Please pull this first large pile of new stuff for 5.10.  The biggest
changes are two new features for the ondisk metadata: one to record the
sizes of the inode btrees in the AG to increase redundancy checks and to
improve mount times; and a second new feature to support timestamps
until the year 2486.  We also fixed a problem where reflinking into a
file that requires synchronous writes wouldn't actually flush the
updates to disk; clean up a fair amount of cruft; and started fixing
some bugs in the realtime volume code.

I anticipate sending a second pull request in a few days to add some
scalability improvements, to schedule deprecation of old features, and
to add fixes for the realtime code.

The branch merges cleanly with upstream as of a few minutes ago, so
please let me know if anything strange happens.

  xfs: ensure that fpunch, fcollapse, and finsert operations are aligned to rt extent size (2020-09-15 20:52:42 -0700)

----------------------------------------------------------------
New code for 5.10:
- Clean up the buffer ioend calling path so that the retry strategy
  isn't quite so scattered everywhere.
- Clean up m_sb_bp handling.
- New feature: storing inode btree counts in the AGI to speed up certain
  mount time per-AG block reservation operatoins and add a little more
  metadata redundancy.
- New feature: Widen inode timestamps and quota grace expiration
  timestamps to support dates through the year 2486.
- Get rid of more of our custom buffer allocation API wrappers.
- Use a proper VLA for shortform xattr structure namevals.
- Force the log after reflinking or deduping into a file that is opened
  with O_SYNC or O_DSYNC.
- Fix some math errors in the realtime allocator.
